The PN terminal box is available in two versions.
• PN Basic terminal box
The PN Basic terminal box can be used if no hot-plug capability is required. The Emergency
Stop circuit can be overridden here by external mechanisms.
• PN Plus terminal box
The PN Plus terminal box features hot-plug capability. This means that it is possible to connect
and disconnect during operation without any disruption.
The emergency stop circuit is automatically maintained during the switching of connectors.
Note
The exterior of the PN terminal box versions only diers in terms of what is printed on the side.
The terminal boxes feature two rotary coding switches (S1 and S2) so that a unique ID can be
set for the purpose of station identication. See Chapter interfaces (Page105).
